Where the swine virus came from? and other virus?

on your opinion? swine virus, sars , ebola, aid virus are phenomenon?
or created by powerful countries for biochemical and nuclear warfare?
ex. sars - > spread in china and neighboring country.
ebola -> may be in africa? ( what country operate big laboratory
in africa?
anthrax -> invented in UK and mass production in US

-------- just an opinion -----------

Your misinformed in saying that anthrax was invented in the UK. It was Robert Koch, a German physician and scientist,that first identified the bacteria which caused the anthrax disease in 1875.All these viruses and even more deadly ones were around way before people ever were.And as far as governments using them for biochemical warfare, they already have. just look to the past for evidence of that.That's not to say there doing it right now but why would they.If they really wanted to release a biochemical agent into different parts of the world to test it for effectiveness or to kill people there are way more effective ways to do it.Take Ebola for instance if they wanted to weaponize it and use it on a global scale there's no doubt that the earth would be a ghost town.

Swine Flu comes from Mexico,i feel someone was bitten(bit of Dawn of the Dead there by the way)and through that,the person who got infected(scenario of 28days)mutated the venom(comparing it to Resident Evil)inside their body,and it became Toxin which tried to reject the host(a bit like Alien)and came through the spores and onto the next person.
Hope this helps clear thing s up
